13a21b0237 Removed "height" of an AVL tree node from its Profile. This is 
implicitly captured by using the addresses of its children in the
profile.

33bbed8f2a Added implementation of immutable (functional) maps and sets, as 
implemented on top of a functional AVL tree.  The AVL balancing code
is inspired by the OCaml implementation of Map, which also uses a functional
AVL tree.

Documentation is currently limited and cleanups are planned, but this code
compiles and has been tested.

68e53ad6cb Add a new function tcExtract for extracting a bignum from an 
arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

643ce59495 Reimplement convertFromUnsignedInteger so it is passed a const bignum. 
It used to modify its argument in-place.

This interface is saner and the implementation more efficient.  It will
be needed for decimal->binary conversion.

ccf596a53e convertFromInteger, as originally written, expected sign-extended 
input.  APInt unfortunately zero-extends signed integers, so Dale
modified the function to expect zero-extended input.  Make this
assumption explicit in the function name.

6de84985a4 improve iplist comments. Switch iplist from allocating its sentinal object (for 
end()) eagerly to allocating it lazily.  This saves a lot of memory for JIT applications
that read a module but don't materialize most of the functions (e.g. 62K for 252.eon).

fe8e14a6c9 This adds a bunch of static functions that implement unsigned 
two's complement bignum arithmetic.  They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

Patch by Neil Booth!

42e4bdf257 When clearing a SmallPtrSet, if the set had a huge capacity, but the 
contents of the set were small, deallocate and shrink the set.  This
avoids having us to memset as much data, significantly speeding up
some pathological cases.  For example, this speeds up the verifier
from 0.3899s to 0.0763 (5.1x) on the testcase from PR1432 in a 
release build.
